**B)** The **BUYERS** are interested in acquiring the titles over the aforementioned mineral rights for carrying out, on the tracts of land and areas covered by them, exploration work seeking the economical exploitation of aluminum ore or bauxite;

**C)**The **SELLER TITLEHOLDER** recognizes the right the **INTERVENING PARTIES** have to share in the income, in the earnings or in the remunerations, of any kind, that may be gained by the **SELLER TITLEHOLDER**, by means of assignment, sale or transfer of the above identified rights for exploration, as well as by any way of economical exploitation of the mineral potential contained therein or identified through exploration work, in accordance with the values and criteria established in the following Clause (PAYMENT).

NOW, THEREFORE, it is hereby agreed by the undersigned Parties to enter into this **AGREEMENT**, which shall be governed by the terms and conditions as follows:

**FIRST CLAUSE  -  TERMS AND DEFINITIONS**

1.1 – This **AGREEMENT** has as premise the will of the Parties in making a pact, by common consent, for the assignment and transfer and the consequent onerous acquisition of the exploration rights held by the **SELLER TITLEHOLDER**, in order to proof the economic basis of the aluminum ore deposits, within the range of the exploration permits granted by the Goiás Superintendency of the DNPM, as above identified by their numbers and processes.

2

1.1.1 – The **BUYERS** will carry out a **Mineral Exploration Program**, hereinafter simply referred as **PROGRAM**, whose objective is to quantify the amount or volume of aluminum ore or bauxite present in the tracts of land object of the exploration permits.

1.2 – For the purposes of this **AGREEMENT**, the term **“Exploration”** is understood as the use of methods and techniques seeking the identification, characterization and quantification of the mineral resources or reserves with economical interest, especially mapping, sample collection and their respective analyses, collection of physical and chemical data from rocks and minerals found in the tracts of land object of the exploration work, as well as the accomplishment of excavations, drilling and the working out of the consequent technical reports in each of their modalities.

1.3 – It is understood as **“ore”**, any natural mineral substance with economical value, either in its raw form, just like it is found naturally, or processed, that is, after being submitted to processes of separation from other materials without economical value, when physicochemical methods are used.  It is called **“ore*****in situ”*** the ore that is not drawn from the place where it is found or naturally occurs, and **“processed ore”** is the ore that undergoes physicochemical processes seeking its separation from other materials.

1.4 – The words **“aluminum ore”** and **“bauxite”** are synonymous, for the purposes of this **AGREEMENT**.

1.5 – For the purposes of this **AGREEMENT**, **“ore volume”** and **“tonnage”** are synonymous terms, corresponding to the amount of ore, measured in tons or other measure of specified mass, contained in the resources to be characterized by the **PROGRAM**.

1.6 – The expression **“mineral resource”**, for the purposes of this **AGREEMENT**, refers to an identifiable concentration of rocks or minerals with economical interest, whose ore content, in amount, grade and/or quality, reasonably indicates that its use is potentially feasible at the present or in the future.  The word **“RESOURCE”**, when written in capital letters, means, for the purpose of this **AGREEMENT**, **“mineral resource”**.  The mineral resource is subdivided into three categories, as follows: inferred mineral resource, indicated mineral resource, and measured mineral resource, which, in this **AGREEMENT**, have the following meanings:

1.6.1 – **Inferred mineral resource** is that part or portion of the mineral resource for which the information regarding volume, grade, quality and other characteristics about the mineralization and its content, are estimated with grounds on inferences made from limited sampling and geological, geochemical or geophysical information, being admitted the continuity or persistence of such characteristics in a defined three-dimensional space through a projection based on reasonable expectations or inferences, whose dimension indicates the potential existence of a mineral deposit; economical.

3

1.6.2 – **Indicated mineral resource** is that part or portion of the mineral resource for which the information regarding volume, grade, quality, morphology, structures and other characteristics of an orebody or mineralized zone present reasonably reliable evidences of continuity or persistence along a space taken into consideration, based on data obtained by direct sampling in ore outcrops and excavations, such as pits, trenches, galleries and drill holes.

1.6.3 – **Measured mineral resource** is that part or portion of the mineral resource for which the information regarding volume, grade, quality, morphology, structures and other characteristics of an orebody or mineralized zone present evidences, with a high degree of reliability, of continuity or persistence along a considered space, starting with confirmation of data obtained by high density direct sampling, accomplished in ore outcrops and excavations, such as pits, trenches, galleries and drill holes, spaced in order to confirm in an irrefutable way the extension and permanence of the properties defining an orebody.

1.7 – The expression **“mineral reserve”** is that part or portion of the mineral resource presenting technical and economical feasibility for mining or mineral production, whose characterization depends, besides the determination of the relevant parameters for mining and ore processing, on the economical return or profitability of said operations.

1.8 – It is understood as the **“best international principles”** the use of methods, techniques and instruments compatible with the best available technology for the carrying out of exploration, as well as the observance of internationally accepted norms for such purpose, especially the Canadian Norm NI-043-101 (National Instrument 043-101), used by the regulating agency of the Canadian stock market, called “Canadian Securities Administrators - CSA”, that establishes guidelines and patterns for public disclosing and reports with information about mineral resources and reserves; the Australian Norm known as the VALMIN Code that establishes criteria and methods for exploration and evaluation of mineral resources and reserves.

1.10 – The expressions **“exploration area”** and **“area under exploration”** are synonymous, and represent an area of 17,783.77 ha (seventeen thousand and seven hundred and eighty-three hectares and seventy-seven ares), over which the **SELLER TITLEHOLDER** holds the exclusive rights for exploration work, as described in the “Second Clause” hereinbelow.

1.11 – The expression **“cubic contents”**, for the purposes of this **AGREEMENT**, is the final purpose or the objective of the exploration, aiming to measure the volume of ore resources or reserves existent in the exploration area.

1.12 – For the purposes of this **AGREEMENT**, it will be considered as **“untrue information”** all information that, in a deliberate way, be transmitted by any one of the parties to the other, with the intention of distorting or omitting the truth about any matter pertinent to the object of this **AGREEMENT**, being excluded 

4

the hypothesis of clerical or involuntary error, and it up to the injured Party to prove the malicious intent of the other.
